In the conventional menses a-htill-Qw cylinder is mounted onashaftpassiiigf'through its geometrical center; the handle is rotatively secured to the shaft? The convex"- lateral surface is perforated, so that wnen the cylinder is filled with a coloring powder (usually pulverized lime) and rolled along the ground or earth, the powder is precipi tated on to the ground, thereby forming a streak over the cylinder path. It is desirable to have a clearly defined line of the width of the convex lateral cylinder surface, but owing to the fact that the powder is always sifting through at least one half of the cylinder, the powder has quite a distance to fall 2'. e., the diameter of the cylinder. The cylinder must be made reasonably large to be the container for a considerable amount of the powder to prevent frequent refillings. The minimum reasonable diameters of such cylinders approximates one foot. The powder being fine spreads and forms a streak instead of the required line.

In order to mark a straight line of any cons derable length, great precision, and

In the drawings, numeral 6 designates a powder magazine formed; i of i three. principal parts-viz; the sides 7 and the annuluse8.

The sides? and; I annulus- 8 are fitted. together byline ns' of the annular groves 10 formed at the heryaof' the sides 7.: 11 designates anal fivtliie geometrical center 0t the-powden 12" hivirfg tlireads 13 on both: extremities; The sides 7 are countersunk at 14: to permit entrance of the nuts 15' which are screwed on to the bolt 13 as shown by Fig. 2. By tightening the nuts 15 on the bolt 12 in the countersunk portions 14 of the sides 7, the sides 7 are tightened on to the annulus 8. Mounted rotatively on the bolt 12,

exteriorly adjacent the nuts 15, is the guard,

16. The washers 17 are then placed on the bolt 12 and then the prongs 18 are rotatively secured to the bolt 12 exteriorly to the washer 17. The pins 19 piercing the bolt 12 near its extremities prevents the prongs from disengaging the bolt 12. The prongs 18 are firmly secured to the handle 20 by means of the bolts and nuts 21. The guard 16 is inclosed front and rear as shown by the overturned edges 22 in Fig. 1 of the inclosing element. The guard 16 is fastened to the bolt 12 by means of the slot 23. By means of this slot relative vertical movement of the guard and the powder magazine is made possible. The front and rear end ef h u d r se d e9 a not re ;is anen'larged detail plan of the;

The guard 16, near its "lower edge has formed the corrugation 24 for the purpose of preventing the guard from sinking too deeply into the ground. Formed in one of the zine. The cover 26 for this opening 25 consists of a scoop as shown in Figs. 4 and 5, with the lid portion 27 and the knob 28. The hole 25 has two notches 29 formed in its side for the reception of the two hooks 30. By inserting the cover26 into the opening 25 so that the hooks 30 will register with the notches 29 and then pushing the cover 26 inwardly, the hooks 30 will be positioned under the edges lof the opening 25. By turning the cover 26, the hooks 30 will be placed under the edges 31 and hence the cover 26 will be firmly but detachably se-' cured in the opening-25. This cover and scoop is simple and performs the dual function of a scoop for the powder and a cover for the opening into the magazine. Owing to its structure it cannot become inoperative on account of dirt, etc., as is the case with all the conventional covers now on the market. follows. 7

By amanual application to the handle 20, the marker is moved over the ground to be marked. The guard 16, holds the powder within its narrow confines until the powder reaches the ground, the corrugation 2 L preventing the guard from sinking farther into the ground than is desired. Furthermore owing to the large surface now in contact with, and supported .calpowder magazine, .on its periphery, and an opening in its side I forthe reception of powder, a guard com-, sides 7, is the hole 25 through' which the powder is placed in the maga-' and guard secured to said The operation of my device is as by the ground, on ac' count-of-the guard 16, a straight line of almost indefinite length can be made.

What I have illustrated and described and mean to secure by Letters Patent is:

1. In combination with a hollow cylindrihaving perforations posed of two trapezoidal shaped members spaced apart bysupports and having curved ends, for confining the powder within selectable limits, and a shaft, said magazine shaft, said magazine positioned within said guard.

2. In combination with a hollow cylinder having perforations on its lateral convex surface, and means for entrance to said cylinder on its side, a combination scoop, disintegrator and cover for said entrance means, consisting of a cylinder portion with the one extremity sealed by a disk and means for selectively securing said scoop to said means for entrance to said cylinder so that the cylinder portion of said scoop when in position will protrude in said hollow. cylinder, a guard enveloping the lower half of said cylinder, with a corrugation formed longitudinally near, its lower extremity and its front and rear-portions curved, a shaft and a handle, said cylinder, said guard, and said handle secured to said shaft and means for moving said guard vertically relative to said cylinder, substantially for the purposes described.

In testimony whereof, I have signed my name to this specification in presence of two subscribing witnesses. JOHN ARTHUR BRANDT.
